Title: Portable acoustic system
Inventor: MINAGAWA TETSUO
IPC: G11B20/10
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a portable acoustic system by which the time difference of data transfer caused by difference in a network line between a transmitting device and a receiving device is cancelled by controlling the timing of music data which is outputted from a reproducing part based on the time difference of data transfer between plural channels. SOLUTION: When the signal originating part 9 of the reproducing part 1 originates a time difference measuring signal to the plural channels after the reproducing part 1 is connected to a mobile reproducing part 3 by the plural- channel line, the time difference measuring part 22 of the mobile reproducing part 3 measures the time difference of data transfer between the plural channels and returns the time difference signal to the time control part 10 of the reproducing part 1. The time control part 10 controls the timing for outputting music data from a buffer 6 so as to prevent the time difference of data transfer in the plural-channel line form occurring. Thus, the portable acoustic system by which music information with little sound quality deterioration is head in the mobile reproducing part (portable equipment) 3 is obtained.

Title: Combustion method for fuel oil utilizing waste heat
Inventor: MIURA MITSUGI
IPC: F23D11/24
Filed: 1981-12-28
Abstract: PURPOSE:To increase the thermal efficiency and to enhance the energy saving effect of a combustion furnace by utilizing waste heat from exhaust gas, by burning minute oil droplets with exhaust gas which contains produced gas, together with combustion air, after the diameters of a part of sprayed oil droplets are made small by evaporating them by the heat of exhaust gas. CONSTITUTION:The fuel oil in a reservoir tank 1 is sucked up by a pump 2 and is sprayed into a circulating duct 17 from a nozzle 14, and at the same time, a part of exhaust gas in an exhaust duct 15 is also sucked into the circulating duct 17 by an induced draft fan 16, by means of producing a swirl flow in the duct 17. Because the circulating duct 17 is slanted upwardly, the diameters of oil droplets sprayed into the duct 17 gradually become smaller from the outside, being vaporized by the heat of exhaust gas. Then the oil droplets are centrifugally separated further, and minute oil droplets only and gas are circulated in a furnace 18 to be burnt together with the air fed from an air feed pipe 19. By this method, the oil droplets turn into minute particles while they are heated by the heat of exhaust gas, and the combustion efficiency of the furnace can be increased and energy is saved, by burning these minute oil droplets with the gas.

Title: Speed change control valve for toroidal continuously variable transmission
Inventor: NAKANO MASAKI
IPC: F16H61/14
Filed: 1991-08-01
Abstract: PURPOSE:To miniaturize a stepping motor by providing a oil chamber to assist the springing force of a spring interposed between the speed change ratio command member of a toroidal continuously variable transmission with a lock up and its speed change command valve for reducing the output of the stepping motor to drive the speed change ratio command member. CONSTITUTION:A weak spring 88 is interposed between a spool 72 serving as the speed change ratio command member of a speed change control valve 64 and a spool valve body 74 serving as a speed change command valve, and an oil chamber 92 to supply hydraulic pressure for assisting the springing force of the spring 88 is provided between the spool 72 and the spool valve body 74. In order to make the oil chamber 92 communicate with a drain port 64b after a commanded speed change ratio attains the maximum speed change ratio, the spool 72 only compresses the spring 88 to make ports 64d, 64e mutually connect for displaying the function of a switch valve to release a locking up mechanism. Thus the output of a stepping motor can be reduced in consequence of the use of the weak spring.

Title: Anchor bolt and manufacture thereof
Inventor: TAKEUCHI HIROYOSHI
IPC: E02D27/00
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To make the strength of a bolt forming part higher than that of a non-treated part. SOLUTION: Surface protrusions 3, 3a at an end of an anchor bolt 1 only are deformed into a nearly flat shape by cold plastic forming and such formed end 5 is formed into a nearly cylindrical column having a diameter nearly equal to that of a base part 2 of the anchor bolt 1, and an internal thread 6 is formed on the formed end 5 by cold plastic forming such as thread rolling. Thus by causing cold plastic deformation on the protrusions 3, 3a and forming the internal thread 6, work hardening is effected so that the strength of the formed end 5, where a bolt is formed, can be made higher than that of a part which is not deformed. In this case, plastic deformation of the protrusions 3, 3a and forming of internal thread requires relatively small working force and strength higher than that of a base material can be obtained and hence an anchor bolt having a larger diameter is not required.

Abstract: PROBLEM TO BE SOLVED: To improve stiffness, lightweightendness and damping property of C-shaped arm by filling a damping material in a cavity of approximately C- shaped arm supporting an X-ray generating means and an X-ray detecting means opposing each other. SOLUTION: Damping material 12-1 and 12-2 are injected into a cavity of C-shaped arms 11-1 and 11-2. Foamed urethane, etc., is used as the vibration absorber 12-1 and 12-2. The injection is conducted by filling a material previously foamed or an expandable material to be foamed after filling. By using this constitution, vibration generated at X-ray tube and transferred to C-shaped arm 11-1 and 11-2 is absorbed by the damping material 12-1 and 12-2 filling the cavity of the C-shaped arm and damped out. Thereby, the vibration is not transferred to the X-ray equipment (radiography equipment).

Abstract: PROBLEM TO BE SOLVED: To obtain higher efficiency by controlling a base current to reduce a sum of continuity loss and drive power based on the detected value of collector current or drain current, in a semiconductor switching element of a power converter. SOLUTION: When a drive circuit is turned on, a collector current of a transistor 5 is detected with a current detector 6 and a current detection signal is inputted to a current command value operator 7, an optimum base current value is calculated depending on the value of collector current, based on this current detected signal, and the calculation result is transferred to a controller 8 as a current command signal. However in the drive circuit, an output current of the drive circuit is detected with a current detector 9, and the current detection signal is inputted to the controller 8.  A control signal for controlling the on/off operation of the switching element 12 and auxiliary rectifying element 14 is generated, so that an output current matches with a current command value, based on the current command signal from the operator 7 and real current signal from the current detector 9. As a result, the sum of the continuity loss and drive current can always be minimized.

SOLUTION: A detection circuit 1 has a reference voltage VCC, a wire 6a is connected to a parking brake(PB) signal switch 6 and a state of the PB is given to the circuit 1. A voltage 0 is given to the circuit 1 from the switch 6 when the PB is set ON, a built-in battery voltage is applied when the PB is set OFF, a voltage of 13.8V is given to the circuit 1 in the case of usual charging. When the PB is set ON, an output signal PBCON of the circuit 1 goes to an L by a current flowing from the television receiver VCC point to the switch 6 and the signal PBON goes to an H level. When the PB is set OFF, a current flows from the switch 6 to the VCC and the signals PBCON, PBON go to an L level. On the other hand, when the wire 6a is not connected, the signals PBCON, PBON go to an H level.  Thus, the presence of connection of the wire 6a is discriminated by the signal PBCON and the ON/OFF of the PB is discriminated by the signal PBON and used for controlling the video display control circuit.
